Abstract
In this paper, a power control strategy based on feedback linearization (FL) control has been proposed at the rotor-side converter (RSC) of the doubly-fed induction generator (DFIG) wind turbine system under unbalanced grid voltage. With this method, the nonlinear model is linearized, not by small signal analysis, which makes it simpler to design the controllers. Furthermore, the oscillations of active power and generator torque can be much reduced. The effectiveness of the proposed methods is verified by the simulation results for the 2 [MW]-DFIG wind turbine system under unbalanced grid voltage conditions.
